' DEMOUNTAIBLE RIM.

To all whom it may concern."

Be it known that I, CHESTER C. HAR- BRIDGE a resident of Detroit, inthe county of Wayne and State of Niichigan, have mvented certain new and useful Improvements in Demounta-ble Rims, ofwhich the following is a full, clear; and exact description.

The invention relates to wheels with de mountable'tire rims and one objectthereof is to provide improved means for detachably holding and positioning the demountable rim on the wheel body. 7 Another object of the invention is to prolsvide an improved locking device for securing atsplit-rim on a wheel body so that both ends of the rim adjacent the split will be rigidly locked to the wheel against relative lateral movement and against separation by '20 the wedges usually employed for securing the rim on the wheel. Another object of the invention is to dispense with the necessity of securing lugs or lates to the rim or the band on the wheel or the purpose of spacing the rim on the wheel and providing bearings for the inner faces of the rim, and this object is obtained by outwardly pressing or denting portions of the band which is rigid on the wheel before the band is fitted to the wheel felly.

Lastly, the invention designs to provide an improved construction for supporting a de mountable rim on the wheel-body.

The invention consists in the'several novel .35 features hereinafter setforth and more particularly defined by claims at the conclusion hereof. In the drawings: Figure 1 is a plan v ew of the rim joint, part of the felly band being broken away. Fig. 2 is a side elevation of a portion of the rim and felly band at the joint of the rim. F1g-."-3 1s a side elevat1on of a wheel embodying'the inventlon, parts being broken away. Fig. 4 1s a sectlom taken on the line 14 of Fig. 3. Fig. .5 is a section taken on the line 5+5* of Fig. 3. Fig. 6 is a section taken on the line 66 of Fig. 3 showing the tire in place on the rim. Fig. 7 is a detail plan of the'portlon of the rim adjacentthe line 6-6 of Fig. 3.

The wheel comprises a felly 3 and a'metal- 'lic band 1 which is rigidly secured tothe felly. This band'isprovided with aseat-flange 2 for one side of the demountablerim. Bolts )7 Specification of Letters Patent.

by nuts 11; to removabiy secure the rim on the wheel; Wedge lugs idiit between the run and band 1, which. necessitatesa space Patented Dec. 21,. 915. Application filed Dec mber 29, 1913. Serial No. 809,140. i

between the periphery of and the 'mner face of the rim. Hereteztore, it has been the practice to secure piates or studs either on the band or on the rim, or both, to provide bearings for the rim against flexure of the rim between the wedge ings when the rim is on the wheei, present in vention dispenses with the'necessity of these plates by indenting the band, as at 4, to provide bearingsfor the inner face of the rim and by indenting the rim as at 1. These indented portions, besides avoiding the necessity of securing studs or plates to the band or rim, avoid the necessity of drilling the band or rim for attachment of the studs or pivots for theplates. The bearing-faces of these indented portions are inclined to cause the rim to easily slip into place and to avoid unnecessary clearance and thereby produce a snug fit between these faces, which will avoid squeaking when the wheel is run ning over the road.

The rim is adapted to hold a pneumatic tire of usual construction and comprises a -main strip 5 which is formed with integral tire-engaging side-flanges'G and with a gap. A filler-section 9 for sald'gap is formed with integral corresponding tire-holding flanges and is adapted to be removed to permit the ends of the mainstrip to be flexed in remo'v ing the rim from the tire, or in placing a tire thereon. The filler-piece has pivoted thereto a plate 21 which is formed with hooks 21, adapted to engage studs 22 on the ends of the main strip, respectively, and to lock said ends .against longitudinal play.

These studs- 22 are provided with enlarged heads 22 which are adapted to enter openings or recesses formed in band 1 to position the rim on the wheel when placed thereon.

The tire-valve extends through an opening formed in a hollow rivet 23 which pivotally connects plate 21 and the-filler-section. Said v rivet has an outwardly projecting head which will pass into a hole 24 formed inthe band 1 and felly 3 of the wheel-body to lock the filler-piece to-thewheel-band when th rim is on the wheel-body. X,

" [111' practice it has been found that it de sirable to provide interlocking means be-i tween the ends of a split rim or one having-.- a gap formed therein, and in the wheel-band,

. excessive spreadingby the wedge-lugs. For I i this purpose, plates 17 are secured to the inthe .rim respectively and plates 18 are riveted on the outer face on periphery of band 1. These plates are adapted t -fit in thespace formed between the base of the rim whereby bothends will be locked against lateral movement relatively tothe band 1 and relatively to each other and ,to prevent ner face of the ends of the main strip 5 of and the periphery of Wheel band 1, so that they will also serveas hearing plates between the rim and the hand. To secure a I rim against lateral movement on the band,

plates 17 are provided with V-shaped or tapered ends 17 which fitrespectively into correspondingly shaped recesses 18? in the plates 18 when the rim is placed upon the hand. These V-shaped terminals exemplify an interfitting-connection between the rim and the wheel-band which will secure the- 7 ends of the mainstrip against relative lat-1' eral movement on the band and against. .sprea'ding sufficiently to leave gaps betweenv the-filler-section and the rim-ends.

When a tire is tobe placed on the rim,

filler-section 19 may be removed by releasing plate 21-from the studs 22 so that the ends.

. ofthe main strip 5 of the rim may be flexed a to facilitate placing the rim in the the or removing it therefrdmi' When the plate 21' I is in operative" position and the rim with the tire thereon is secured to the wheel, the

f interfittingends of plates 17 and 18 will secure the rim against lateral movement in either direction and the indented portions 4, 1 of the band-will provide bearing surfaces between the rim and the band. In placing the rim on the-wheel, the rim is angled laterally while the tire-valve drops into its opening-inthe wheel, and plates 17' drop between plates 18 on the band. Thenthe rim is swung laterally into position around "the. wheel-band when the inclined bearingfaces of the band and the rim will pass into engagement. The wedge lugs are then forced into the space between the band for the rim by nuts 18 7 When the rim is thus secured on the wheel, the rim ends will be secured against relative transverse movementor so that their ends cannot be shifted out of alinement, by the interlocking plates 17, 18. It sometimes occurs, in practice,

. that there is a little looseness-or wear between studs 22 and the locking plate 21.

The interlocking, plates 17 and18, besides holding the ends alined when the rim ison the Wheel, serve to limit the expansion of therim in event of this looseness.

1 The-, invention i s --not to beiunderstood as may be modified within the scope of the restricted to thedetails set forth, since these appended claims without departing from d the spirit and scope of the invention.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is: f 1. The combination with a wheel body, of a tire rim adapted to extend around the body With a spacebetween the peripheryof the wheel body and the inner faceof'the rim, interlocking devices between the rim and the wheel comprising elements secured on and projecting. from the inner face of the rim and the outer face of the wheel-body,

respectively,'and havingrecessed and interfitting ends, respectively, to secure the rim against lateral and longitudinal movement on the wheel-body, and means independent of said devices for removably securing the rim on the wheel-body.

2. The combination with a wheel'body,

'of a transversely split tire rim' adapted to extend around the body with a space between the periphery of the wheelbody and the inner face of the rim, interlocking devices between the ends and the wheel, each device comprising elements secured .on
